About This Data
The 1986 Mazda B2000 has an MOT pass rate of 68.1% based on 47 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 120,359 miles on the odometer. With a 31.9% failure rate, the 1986 B2000 is rated as "Good" for MOT reliability.
If you own or are considering buying a 1986 Mazda B2000, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to road wheels: Visually inspect wheels for cracks, especially around the spokes and rim. Check that all wheel nuts are present and tightened. Look for signs of impact damage on alloy wheels. With an average mileage of 120,359 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Road Wheels — 8.5% of failures
Road Wheels issues account for 8.5% of MOT failures on 1986 Mazda B2000 models. Wheel failures include cracked or severely corroded alloy wheels, missing or loose wheel nuts, and wheels that are insecurely attached. These are safety-critical and relatively rare compared to tyre failures. Typical repair costs: £100–400 per wheel. Pre-MOT check: Visually inspect wheels for cracks, especially around the spokes and rim. Check that all wheel nuts are present and tightened. Look for signs of impact damage on alloy wheels.
Lamps, Reflectors and Electrical Equipment — 6.4% of failures
Lamps, Reflectors and Electrical Equipment issues account for 6.4% of MOT failures on 1986 Mazda B2000 models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
Exhaust, Fuel and Emissions — 4.3% of failures
Exhaust, Fuel and Emissions issues account for 4.3% of MOT failures on 1986 Mazda B2000 models. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.
